Hi, I am new to the drone world. If I try to take off, an error: "Takeoff error: Check IMU and Motor" comes up. I have updated all the firmware and calibrated the IMU several  without success. Help please

Welcome to the Spark, Are you using the remote control or only a phone or tablet or gesture control?

Take a picture, or video from trouble. Insuccifient  information!

Hi, Sorry for the troubles that it caused. Where did you purchase the unit? What happened to your drone prior to this issue? I would recommend restoring factory defaults and refresh the firmware using the DJI Assistant 2. It is advisable to reboot the aircraft after using the application and please re-calibrate the IMU and compass as well. Thank you for the support. Please see the link below for you to download the DJI Assistant 2 and video tutorial.
